Both the FBI and CIA have concluded that Russia interfered with the elections to help Trump win. 

But Trump has dismissed the allegations, saying there is no proof that Russia hacked into the email accounts of Democratic National Committee and Clinton campaign staffers. 

McCain said while he hasn't heard Trump criticize Russian President Vladimir Putin, he suspects that "reality is going to intercede at one point or another." 

McCain instead focused his criticisms on President Obama, saying the U.S. has been "totally paralyzed" in responding to Russia's attacks. 

"The fact is that they're hacking every single day in other areas of our military and other aspects of American life, and we have no strategy, nor do we have any policy toward that," he said. 

"This is serious business," McCain said. 

"If they're able to do harm to the electoral process, then they can destroy democracy."
